The purpose of this study is to understand the effect of ground conditions on microbial cementation in cohesionless soils. Since the method of microbial cementation is still at the experimental stage, for its practical use in the field, a number of laboratory experiments are required for the quantification of microbial cementation under various ground conditions, such as relative densities, rel...
The pathophysiological characteristics of Phlegm-stasis Cementation Syndrome in Coronary Heart Disease (CHD) has been summarized in this article. According to epidemiological investigations, phlegm-stasis cementation syndrome has become a dominant syndrome in CHD along with the improvement in living and dietary condition. The interaction between blood stasis and phlegm turbidity that is called ...
This article describes the different materials and techniques that are used for adhesive cementation. Particular attention is given to treatments suitable for dentin, as well as the selection of surface treatments for various restorative materials. Factors related to the durability and stability of the adhesive process, as well as the clinical and laboratory procedures required for cementation,...
BACKGROUND Intralesional excision with curettage is the standard method of giant cell tumor (GCT) treatment, but the ideal filling material after curettage remains controversial. The purpose of this study was to compare the oncological and functional outcomes which underwent cementation or bone grafting after GCT curettage around the knee. METHODS We reported 136 cases with GCTs in distal fem...
Background: Resin cements are widely used for cementation of FRC posts, but their bond strength can be influenced by cement type and cementation technique. The aim of this study was to determine the effect of type of resin cement and cementation technique on the bond strength of fiber posts. Methods: Forty five extracted mandibular premolars with a minimum roo...
BACKGROUND The increasing number of revision knee arthroplasty result in the more frequently use of a constraint implant but results from previous reports are difficult to interpret. The purpose of this study was to compare the long-term outcomes of superficial cemented versus metaphyseal cemented in revision total knee arthroplasty with a condylar constrained arthroplasty. METHODS The study ...
BACKGROUND Glenoid component survival is critical to good long-term outcomes in total shoulder arthroplasty. Optimizing the fixation environment is paramount. The purpose of this study was to compare two glenoid cementing techniques for fixation in total shoulder arthroplasty. METHODS Sixteen cadaveric specimens were randomized to receive peg-only cementation (CPEG) or full back-side cementat...
counties (Torrent et al., 1980), and in soils formed in late The morphologic development of soils on marine terraces is a function of terrace age and geomorphic evolution. In this study, inter relationships between terrace landscape evolution and pedogenic sil ica cementation were investigated. Soil morphology, micromorphol ogy, selective dissolution, penetration resistance, and hydraulic co...
